MACHINE FOR GLAZING TUBES, 80c.

SPECIFICATION forming part of Letters Patent No. 760,104, dated May 17, 1904.

Application filed July 29, 1903. Serial No. 167,373. (No model.)

To all whom it may concern: gearing 15 and 16, with shafts 17 and 18, car- Be it known that I, JOSEPH OONDE, a citirying toothed wheels which, through the in- 5 zen of the United States, residing at the city tervention of idlers 19, mesh with toothed of Philadelphia, in the county ofPhiladelphia wheels on the rollers 12 and 13. Thus the and State of Pennsylvania, have invented cerrollers 12 and 13 are rotated, and they are tain new and useful Improvements in Mapositioned in such a way that the carriers 4 chines for Glazing Tubes' and the Like, of when the belts or aprons are moving cause which the following is a specification. the blanks 5 to ride up on top of and between One object of the present invention is to the rolls and also cause the blanks to be car- IO provide a simple, comparatively inexpensive, ried forward through the machine, as will be and reliable machine for. rapidly glazing the described.

These aprons are provided with upwardly- The mode of operation of the foregoing apextending carriers 1 for the blanks 5. The paratus may be described as follows: The 5 aprons run on the wheels 6 and 7, carried by tubes whose ends are to be finished, or shafts 8 and 9., journaled in the bearings which glazed, as it is called, by subjecting them 4 rise from the frame or bed 1. The burners to the heat of the burner, which is all that is 10 constitute one set and the burners 11 annecessary in the case of small tubes for makother set, so that each set comprises apair of ing them smooth, are fed from the chute 27. 9 burners. and they are arranged, as shown, The straight edges of thecarriers receive them transversely and outside of the aprons and and the belts or aprons carry them forward.

45 opposed to each other. Inline with the burn- The motions of the belts or aprons are interers and between the belts or aprons are armittent, so that alternate blanks are present- I ranged a pair of revoluble rollers 12 and 13. ed to each of the sets of burners, and in this 14 is a driving-shaft geared, as by chain way two blanks always are having their ends heated at once. This is accomplished by causing the belts or aprons to traverse the-distance between two carriers after each of its pauses; or, otherwise stated, at each pause one carrier is near each set of rolls, and after the pause the second successive carrier passes the rolls and the third successive carrier stops near the rolls in the place previously occupied by the first carrier! The set of burners and rolls toward the left may be assumed to operate on the blanks marked a" and those to the right on blanks marked'a. Thusablank marked 00 is shown as in position in respect to the lefthand rolls and burners. to the heat of the burners, and their action, combined with the rotation imparted by. the rollers, serves to glaze its ends. At the same time a blank a is in position on the right-hand set of rolls and is being similarly treated. The next motion of the apron causes the blank a to the left to ride over the rolls to the left and a blank 00 to be placed thereon. Similarly the finished blank m to the left of the right-hand rolls rides over thelatter before the blank (1., which previously rode rapidly over the lefthand set of rolls, is positioned on and treated by the right-hand set.

It will be obvious to those killed in the art to which my invention appertains that modifications may be made in detail without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but, I

Having thus described .the nature and ob jects of my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. A machine for simultaneously glazing the ends of a plurality of tubes or blanks which comprises an apron provided with carriers for the blanks, sets of pairs of opposing burners, and means for intermittently shifting the apron to present alternate blanks to each of the sets of burners, substantially as described.

Its ends areexposed' 2. In a machine for glazing both-ends of tubes the combination of endless belts having a spacebetween them and provided-with carriers for the blanks, means for intermittently driving the belts, a pair of opposing burners arranged with the belts between them, revoluble rolls located between the opposing burners and between the belts or carriers and adapted to receive the blanks, and means for positively revolving said rolls in the same direction, substantially as described.

3.,In a machine for glazing both ends of tubes the combination of a pair of belts or aprons having a space between them, means for actuating the belts, triangular carriers extending outward from the belts or aprons, a pair of rolls arranged between the belts or aprons, a pair of opposing burners arranged outside of the aprons and in line with the rolls, and-means for positively revolving the rolls in the same direction, substantially as described. 4. A machine for glazing tubes or blanks which comprises an apron having carriers, means for intermittently driving the apron, rolls onto which the apron feeds the blanks, means for positively revolving said rolls in the same direction and thereby revolving the tubes or blanks, and opposing burners for heating the ends of the rotating tubes or blanks, substantially as described.

5. The combination of rolls arranged adjacent to each other and adapted. to support a blank ortube in rolling contact above and between them, a burner for heating the rotating blank or tube, and means for positively driving said rolls in the same direction, substantially as described.

In testimony whereof I have hereunto signed my name.

JOSEPH CONDE.
